Check division is integer or float solidity
Suppose i have a contract with decimals and total Supply as follow.
How can i check if tokenAmountInWei pass in is integer value in form of ether.
decimals = 18
totalSupply = 1000000
function someFunction(uint tokenAmountInWei)
// check if tokenAmountInWei convert to ether is integer value

This should work:
pragma solidity ^0.4.24;
contract Test
function checkIntegerETH(uint a) public pure returns (bool)
return (a % 1 ether == 0);
Here we are basically confirming that a has no remainder when being divided by 1018 (1 ether).
